BOX BLANK AND BOX MADE THEREFBOM.

Application filed July 16, 1921.

T aZZ whom it may concern:

Be it known that I, ELI P. WILLIAMS, a citizen of the United States, anda resident of McPherson, in the county of McPherson and State of Kansas,have invented certain new and useful Improvements in Box Blanks andBoxes Made Therefrom, of which the following is a description, referencebeing had to the accompanying drawings, forming a part of thisspecification.

The objects of my invention are First: To provide a novel fastener thatis dependable, simple and easy to operate, and will securely fasten andlock together, the parts of boxes and covers for same, made from boxblanks of any description, so the boxes will be rigid, strong anddurable and will not'collapse by ordinary use.

Second: To provide a corner stay to strengthen the corners of boxes andcovers for same, made from box blanks of any de scription.

Boxes in common use, made from box blanks, are not dependable and sooncollapse, owing to the lack of stability of their parts,

caused by the insecure and loosely connecting fasteners used inconstructing the boxes. The fasteners used consist of a hook on the endof an overlapping part of the box blank and a slit in the adjacent partof the box blank or box wall. To fasten together the parts of the box,the hook is hooked over the edge of the box wall in the slit.

Like all hook fasteners, it is liable to come 5 unhooked at any time andis insecure and loose from the start, to the extent of the depth of thecurve that forms the hook. Cmisequently, all boxes made from box blankswhere hook fasteners are used, lack rigidity and strength and inordinary use will soon collapse.

My lock fastener is much better than the hook fasteners now in use inthis, that boxes made from box blanks where my fasteners are used, arerigid, strong and durable, and

will not come unfastened or collapse by ordinary use. One greatadvantage it has over the hook fastener is that the fastening may bemade near the box corner, preferably within one inch of the box corner,and the fastening being so near the box corner adds strength to thecorner stay, the fastener and the box corner. The fastening parts restclose to the box wall and do not interfere with the contents of the boxor the cover.

the corner ofthe box and the notch fastener in position and the parts ofthe box fastened and locked together.

Figure 3, is an exterior View of a folded corner section of the box, ina folded upright position, showing the lock fastener securing andlocking together the parts of the box.

10 designates the main rectangular portion of the blank provided withthe end walls 12 and 18 formed by score lines 1 1 and 15. The side walls16 and 17 are formed by the score lines 18 and 19. At the respectiveends of the side walls 16 and 17 are corner stays 20, which consists offlaps extending beyond the ends of the side walls 16 and 17 and whichhave outwardly inclined edges. The narrow portions of the stays, asindicated at 21, do not come to a point but have widths suflicient toenable the inner ends of the stays to rest against the portion 10 whenthe end walls and side walls are secured together. It is important thatthere be sullicient material in the stays or flaps 20 to provide abearing against the portion 10 so as to brace the perpendicular walls ofthe box.

The end walls are provided with flaps or tongues 22, the tongues 22having notches 23 diametrically opposite the notched portions 26 to formthe projecting portions 241, as shown, and the heads 25 on the ends ofthe flaps or tongues. The shape of the head 25 is quite important, theouter edge of each tongue being curved as at 27. The base port-ion 24 ofeach tongue 22 is cut away so that it will not be quite the width of itssupporting end wall. This is to leave space, as at 28, for the portion21 of the stays and it also permits the box walls, to which flaps 22 areattached, to yield or spring outwardly without tearing or injuring thecorners of the box when the fastening parts of the box corners are putin position.

29 are transverse slits in the walls 16 and 17 and at the inner end ofeach slit is a horizontal slit 129 and a diagonal slit 229.

The length of the slit 29 is approximately equal. to the distancebetween the notches 23 and 26. This is very important because when theparts are tastened together, the portion 26 rests against the slit 129and the notch 23 rests against the outer end'of the slit 20 so thatthere can be no lateral play of the flap or tongue 22 in the slit. Thisis to prevent the accidei'ital disengagement of the tongue from theslitted portion of its complementary side wall.

It is an important feature of my invention that when the blank is puttogether in box form the tongues 25 will be onthe inside of the box andthereby prevent liability of the tongues beingtorn off as well as toprovide a symmetrical attractive and neat structure. The blank is thesame whether the box part resulting therefrom is the bottom or the top,because in order to complete the box, two members are formed from ablank such as shown in Fig. 1 except one is slightly larger than theother and then they are telescoped together.

In connecting the end walls to the side walls, the end andside walls arecreased along the score lines 1 15, 1S and 19. Then the tongue. 25visinrtroduced into the slit 29 andinto the diagonal slit 229, the stay20 being bent over so thatits horizontal, lateral bottom edge 21 willlie against the blank 10, as clearly seen in F 2.

lVhen the tongue has been introduced into the: box as shown in Figs. 2and 3, the notch 23 will receive the boxwall at the top end. ofthe-slit29 and thenotch 26 will lie against the edge of the box wall in the slit129 so that, there will be no lateral play of the tongue, consequently,the tongue cannot bepulled out.

If they slits-29-were longer than the distance between the notches 23and 26, there could be lateral play'of the tongues and consequently,they would readily pull out, this beingwhat usually happens with. the.ordinarytonguesand slitted connection in boxes ofi like generalstructure.

To. I prevent; the. fastening and locking parts ofthe corners ofboxesfrom be-oming detached when onceoin position as sorlrequently. occurs,with boxes now innse, the fastening and locking. parts in this inventionare. so constructed that when the. head of the tongueis through theslits in. the complementaryi box wall and the fastening. andlockingparts are in position, the. fastening and. locking parts areclosed and; looked around ,the neck of the tongue so the tongue.istheld, and. retainedin the slitsand the fastening and lockingparts ofthe corners of boxes are held and retained in position and lockedtogether.

By, reference to Fig. 2 it will be observed that the corner fasteningfor tile, box providesa rigid, secure attachment, theS' yS 20 serving toreinforce the corners of the box and by preventing distortion ofthe endand side walls, eliminate liability of the tongues 25 twisting out ofthe slits. vln actual practice I find that after I have fastened thetongues in the slits as shown in Fig. 2, it is. practically in'ipossiblcfor the tongues 22 to become detached without very carefulmanipi'llation of the box, thereby liability of the accidentaldisengagement is eliminated.

The are on which the curve 27 is formed is designed to allow thetongueorheaded portion 25 to easily enteiwthe slit 2,) so that the outer edge ofthe slit 29will be in the notch 23 and since the, edge-ofnthe notch 2brests on the edge of the slit-129, it will-be seen that'the fasteningwill be held secure.

I do not limit myselfsto the exact details of construction shownbutreserve the right to make such changes in form, proportion and minordetails of construction as properly come within the scope of/myi,invention.

Whatl claim and desire to secure by Letters-Patent is:
